BART riders beware: Friday night Tube delays

Starting at 10 p.m. and continuing until the system shuts down after midnight, BART will be using just one of the two tunnels beneath the bay, forcing trains to share a single set of tracks. Passengers traveling in either direction through the tube should be ready for possible delays of 10-15 minutes.

The shutdown of one tunnel will allow BART to perform track maintenance. Track work will also slow travel between Rockridge and Pittssburg/Baypoint stations from 8 a.m.-3 p.m. on Saturday.
